Excuse the ignorance on this one, but this looks very much like a fridge that has been converted, am I correct?
Just one question, if it is a fridge is it still plugged in to the mains? The only reason I ask it that I have an old freezer that could be made into a humi, but as soon as you turn it off and close the door it gets covered in mould and stinks.
I therefore assume that you need to keep it turned on (except that you wouldn't if you were using a freezer!)
Presumably if you are going down this route you should use an old chiller cabinet commonly found in bars?
As I said, excuse the ignorance, I'm from Barcelona.
